Iron doped zinc sulphide nanoparticles (ZnS: Fe) have been synthesized by co-precipitation method at room temperature. X-ray diffraction together with photoluminescence analysis established that iron occupies the lattice sites in host zinc sulphide lattice. The emission intensity is further quenched in iron doped nanoparticles as compared to un-doped one. This is attributed to the formation of electron-trap...
Diluted magnetic semiconducting (DMS) ZnS:Ni (Ni=0, 1, 3 and 5at%) nanoparticles were synthesized by the refluxing technique at 80°C. X-ray diffraction studies showed that undoped ZnS and Ni doped ZnS nanoparticles exhibited the expected zinc blende structure. X-ray photoelectron spectroscopy results revealed that the Ni ions existed in a +2 state in these nanoparticles. Reflectance measurements showed...
